LPDDR4 Benchmarks
#1
I'm interested in what benchmarks changed with the move from LPDDR3 to LPDDR4.
To start with, specifically what is the output of

Code:
cryptsetup benchmark
with LPDDR4?

Once there is a Linux image available I'll post benchmarks.

Currently LPDDR4 set to PC-1600 parameter and will push up in near future. This means expects as PC-1600 type of performance result first.

Just for fun I used
termux-ubuntu
on my phone but it only got part way ;

Code:
cryptsetup benchmark
# Tests are approximate using memory only (no storage IO).
PBKDF2-sha1       859488 iterations per second for 256-bit key
PBKDF2-sha256    1699474 iterations per second for 256-bit key
PBKDF2-sha512     497426 iterations per second for 256-bit key
PBKDF2-ripemd160  447344 iterations per second for 256-bit key
PBKDF2-whirlpool  168907 iterations per second for 256-bit key
argon2i       4 iterations, 664468 memory, 4 parallel threads (CPUs) for 256-bit key (requested 2000 ms time)
argon2id      4 iterations, 726194 memory, 4 parallel threads (CPUs) for 256-bit key (requested 2000 ms time)
Required kernel crypto interface not available.
Ensure you have algif_skcipher kernel module loaded.

On the bionic-containers-rockpro64-0.6.44-239-arm64 image for the ROCKPro64, I got this:

Code:

Thanks pfeerick, looks like The LPDDR4-1600 did not help that particular benchmark which is reasonable as it's likely SOC bound. Odd that N1 was slightly faster 620.1 vs 655.6, but likely just some minor software diffrence...
what kernel was that on?
Code:
uname -r

Not sure, I'll check in the morning. It was the stock for that image though. It's still early days for the images also, so there is still room for improvement.

ROCKPro64 w/ 4GB RAM, bionic-containers-rockpro64-0.6.51-253-arm64.img.xz, kernel 4.4.126-rockchip-ayufan-253

This will likely be a little slower than the previous results where CPU frequency counts - the 0.6.44 was clocked slightly higher with a custom op basically clocking the big CPUs at 2Ghz, and they have since been taken back down to 1.8Ghz.
